目的：了解胰岛素样生长因子Ⅰ(IGFⅠ)对培养关节软骨细胞增殖及代谢的影响。
方法：体外单层培养兔关节软骨细胞,实验组以10,100,200ng/mlIGFⅠ作用细胞2、4、6天,对照组不加IGFⅠ作用培养细胞。检测细胞DNA及基质中糖醛酸含量。用流式细胞仪分析在100ng/mlIGFⅠ作用下细胞周期亚时相。
结果：IGFⅠ在10～100ng/ml浓度范围内,对培养软骨细胞增殖和代谢有促进作用,以100ng/ml浓度作用效果最佳。细胞周期分析,实验组DNA合成前期(G1期)较对照组缩短。
结论：IGFⅠ促进软骨细胞的增殖与代谢,且通过缩短细胞G1期而缩短细胞周期。 |

Abstract:
Objective:To investigate the effect of insulin like growth factor Ⅰ(IGF Ⅰ) on proliferation and metabolism of cultured articular chondrocytes.
Methods:The monolayer chondrocytes obtained from rabbit were cultured.The experimental group was treated with IGF Ⅰ at doses ranging from 10,100,200ng/ml at 2,4,and 6 days while the control group was cultured without IGF Ⅰ.The cell DNA content and matrical glucuronic acid were maesured.The cell cycle of chondrocytes treaed with IGF Ⅰ at 100ng/ml was determined by flow cytometer.
Results:IGF Ⅰ stimulated proliferation and metabolism of chondrocytes at doses ranging from 10 to 100ng/ml.Maximal effect of stimulation occurred at 100ng/ml after treatment.The time of DNA synthesis(G1) was shorter in experimental group than in control group.]
Conclusion:IGF Ⅰ stimulated proliferation and metabolism of chondrocytes and shortened the time needed for G1 phase. |
